Read Summaries of Systematic Reviews

March 25, 2010

Wouldn’t it be nice if you could find all the systematic reviews pertaining to dentistry in one place?  You can!

The American Dental Association (ADA)  Evidence Based Dentistry website includes a database of systematic reviews in oral health. The reviews may be found by searching the site or using the ADA’s drill down topic menu.

Even better, the ADA provides  critical summaries of many of these  systematic reviews.  Critical summaries are brief, concise assessments of a review that are written by ADA Evidence Reviewers.  These reviewers are trained  in the critical appraisal of scientific literature.

Here is a list of the most recently published critical summaries:


Xylitol and Dental Caries

July 31, 2009

Xylitol is a natural sugar alcohol found in some food products and used as a sugar substitute.  Studies strongly suggest that xylitol is non-cariogenic.  That is, xylitol decreases streptococcus mutans levels in plaque and saliva, thus reducing the incidence of dental caries.

Despite these findings, there is little information on the amount of xylitol needed in food products to be effective.  In addition, xylitol is not a clearly labeled ingredient on food packages.

According to the HealthPartners Dental Group and Clinics caries guideline, “xylitol can significantly reduce caries progression if used for five minutes 3-4 times a day after meals and snacks.”  The guideline also states that at least 4 grams of xylitol should be consumed daily.”

In its revised Policy on the use of Xlyitol in Caries Prevention, The American Academy of Pediatric Dentistry stated that they support preventive strategies that use sugar substitutes.  However, the academy recommends further research  and encourages clear labeling of products which contain xylitol.


ADA Launches Center for Evidence-Based Dentistry Web Site

March 10, 2009

I am excited to announce the all new Evidence-Based Dentistry web site from the American Dental Association, prepared by dentists for dentists and their patients.  This site provides access to the most current and clinically relevant information.

Nicely organized by three categories, the site brings together:

  • A Database of systematic reviews—Organized by topic, currently over 1300 reviews, some with clinical summaries (short and concise assessments of a systematic review written by trained ADA Evidence Reviewers)
  • Clinical recommendations—tools that can be used when making evidence-based clinical treatment decisions
  • Links to evidence-based dentistry resources—Links to outside resources including tutorials, glossaries and databases

I highly recommend that you explore the site.

Does Treating Gum Disease Reduce the Incidence of Preterm Birth?

February 4, 2009

Previous research has suggested a link between periodontal disease and premature birth.  Consequently, pregnant woman have been encouraged to undergo periodontal treatment to reduce these risks.

However, recent studies conducted at the Univeristy of North Carolina’s School of Dentistry revealed no significant differences in pregnancy outcomes when study participants received treatment, as compared to those participants who did not.

As a result of these findings, the American Academy of Periodontology (AAP) released a statement calling for additional research to “clarify the potential impact that periodontal disease has on the risk of preterm births“.  The AAP also continues to encourage pregnant women to care for their oral health.
